The TOMEI T400M EJ/TS Twin Scroll Turbo Kit is designed for superior performance at very wide range of engine speed with the combination of the IHI center unit and the twin scroll turbine housing. Drop-in design for ease of installation, yet promises a great drivability from street to track. The reinforced wastegate actuator helps a stable boost under high engine speed.
Features
- CHRA made by IHI + Fully divided twin scroll ports
- The new turbine housing with fully divided twin scroll ports all the way to the turbine wheel helps smooth exhaust flow by eliminating interfere against each flow. Designed to make the most of the twin scroll system to minimize the turbo lag while keeping the torque at low speed range and gaining peak power.
- T400M-EJ/TS has been designed to best match the floating bearing CHRA developed with IHI. Ultra low friction from the optimized rotating efficiency helps quick spool and superior durability.
- Easy bolt-on installation, no modifications required. The short parts required for the installation, such as hose, gaskets and studs come with the kit. (Kit does not include suction hose or vacuum tube, prepare individually as necessary.)
- Remarkable stability under high boost.
Notes
- Turbo Suction Hose also needs to be replaced when install on GDB.

Tomei was founded in 1968 by members of the Johoku Riders motorcycle club, among them Nissan works driver Seiichi Suzuki. It began as a racing engine builder for Nissan engines only, and its work on the Nissan L-series and later the RB and SR engines made its name. The company took the name Tomei Powered when it moved to Machida, Tokyo, in 1994.
Tomei now develops parts for many Japanese engines, Mitsubishi, Subaru and Toyota as well as Nissan: camshafts, valve train parts, pistons, connecting rods and crankshafts, complete engines, and exhaust systems such as its well-known Expreme titanium range.
